Rare Earth Magnets Rare Earth Oxide
Who separates mixed rare earth concentrate into individual oxides in the United States?
What it is
A separated single rare earth oxide, or a defined mixture such as NdPr oxide, produced by solvent extraction from mixed concentrate. Separation is the hard step in rare earths: the elements are chemically almost identical, so splitting them takes hundreds of extraction stages, and it is where the global supply chain concentrates.
- Typical dimensions
- Sold by mass and assay, commonly at 99 to 99.9 percent purity of the named oxide.
- Also known as
- REO, NdPr oxide, neodymium oxide, praseodymium oxide, didymium oxide
Suppliers
Grouped by what they actually are. A mill and a distributor answer different needs.

Energy Fuels Inc. Verified
Separated NdPr oxide, up to 1,000 tpa. The company states its US-produced heavy rare earth oxide has been qualified for use in permanent magnets, and announced first US primary production of heavy rare earth material in decades in March 2026. IMPORTANT: this is an OXIDE producer only. It does not reduce to metal, and states it will rely on pending acquisitions for downstream metal and magnet production.
